Packera crocata
Packera cymbalaria
Packera crocata is characterized by deep yellow to reddish orange corollas. Some collectors have noted that there may be evidence for hybridization between P. crocata and P. dimorphophylla; the relationship between the two species needs further study.

Packera cymbalaria occurs in three, disjunct regions: western Alaska eastward into western N.W.T. and south into northwestern British Columbia; Newfoundland and the Gaspé Peninsula, Quebec; and Siberia. Considerable morphologic overlap exists between western and eastern populations in North America; western populations have slightly different flavonoid chemistries and chromosome numbers. Western populations are either diploid or tetraploid; eastern populations are hexaploid. The correct name for this species may prove to be Packera heterophylla (Fischer) E. Wiebe, based on Cineraria heterophylla Fischer.
